Frequently Asked Questions
How much current can each contact in UMPT-03-01.5-G-VT-SM-WT-K handle, and what total power can the 3-position connector deliver?
Each contact in the UMPT-03-01.5-G-VT-SM-WT-K is rated at 18 A, so the 3-position connector can carry a maximum of 54 A total when all contacts are used for power distribution. In practice, designers commonly assign 1 or 2 positions to power and the remaining positions to ground returns, with voltage ratings typically in the 12 V to 48 V range depending on the system architecture and derating applied.
What does the gold contact finish on UMPT-03-01.5-G-VT-SM-WT-K contribute to connector reliability in power applications?
The gold (G) contact finish provides a noble metal surface that resists oxidation and maintains contact resistance below 10 milliohms at the rated 18 A current levels. Gold-plated blade contacts are especially important in power connectors where elevated contact resistance would cause resistive heating, voltage drop, and potential thermal runaway at high current densities. Gold finish also supports reliable mating across temperature cycles from -40°C to +105°C typical of industrial power environments.
How does the polarization and keying on UMPT-03-01.5-G-VT-SM-WT-K prevent connector mis-mating in high-current power assemblies?
The polarized and keyed housing on UMPT-03-01.5-G-VT-SM-WT-K physically prevents the connector from being inserted in the wrong orientation, eliminating the risk of reverse polarity connection at 18 A currents that could damage PCB traces, burn out power supply outputs, or trigger short-circuit protection. The keying feature is particularly valuable in board-level power assemblies where multiple similar-looking connectors are placed within a few millimeters of each other.
What lead time should procurement teams plan for when ordering UMPT-03-01.5-G-VT-SM-WT-K for production builds?
The UMPT-03-01.5-G-VT-SM-WT-K has a factory lead time of approximately 10 weeks from SAMTEC. For production programs with monthly consumption, teams should place orders at least 12 to 14 weeks in advance to maintain safety stock of 4 to 6 weeks supply. Checking SAMTEC's authorized distributors for available spot inventory can help fulfill urgent bridge orders while awaiting standard production deliveries.
